Browser Interpretation of Location: Header

Hi Ya'll,

I'd be interested if there is concensus on this one. I have a CGI program
for processing forms which, upon successful submission (i.e., POSTing),
issues a Location header, as follows:


That's it. The server issues a 302 return code.

When using a Netscape 1.2 or Mosaic NCSA 2.0 browser, it works great. It's
an easy way to report a "thank you" message, possibly directing a user
outside the scope of your own location if need be. Unfortunately, SPRY's
2.0 browser returns a server error. After reviewing the server access log,
I can see that it tried to "re-post" the request using (instead of the
original /cgi-bin/doit) /thankyou.html. Yikes!

I've reviewed the HTTP spec, but it was not clear what is the correct
behavior here. Should the browser interpret any redirection as a GET (as
Netscape and Mosaic do), OR, maintain the same operation (in this case,
POST) ? In fact, am I (technically) abusing the ability to override the
Location header by using this methodology. Should I be returning a status
code or something?
